Regarding "Invasive Species" and Trojan Horses 
(Note: This is an excellent -- and brief -- means of understanding the agenda of "invasive" species and those driving this Cash Cow. This is an agenda to control people by controlling their ability to responsibly use their lands and waters. It is an agenda to control all recreation by controlling access by humans whose shoe treads, bicycle and other vehicle tire treads, etc. "MIGHT" or "COULD" spread "invasive seeds" -- all the while never mentioning that birds spread seeds far more widely than people ever could. It is highly recommended that you share this gem widely. A must-read!)

Weeds are weeds, whether native or nonnative. It is almost certain that some of the "invasive weeds" (weeds) are "native weeds" (weeds). Sagebrush, perhaps? It is a native specie.
Confused? Don't feel bad. 
Confusion is part and parcel of the "Invasive Species" agenda.
You see, by definition -- President Clinton's Executive Order 13112, February 3, 1999 -- an "Invasive Species" must be "nonnative to that ecosystem".
Who knows enough to decide what is native to an ecosystem -- and what is not?
The simple answer is: Nobody, really.
Okay, so what to do about that? Here goes:
1. Create a crisis (agenda). "Invasive Species": Natives are "good". Non natives are "bad".
2. Create bureaucracies to deal with this "crisis" -- that didn't exist before February 1999).  
3. For Precautionary Principles, list almost any non-food plant species that is known to be of foreign origin as an "Invasive Species". (Examples: red clover, timothy, brome ... as well as yellow starthistle, the knapweed family, and so on ...)
4. Create "partnerships" with universities, government research units, "environmental" groups, even agriculture organizations -- etc., for the purpose of ... (see No. 5)
5. ...FUNDING. Yes, it all boils down to power and money
From No. 2, we see that it will be the "experts" in the bureaucracies who anoint themselves as the sole authorities to determine what is "Invasive" and what is not. Power.
From No. 5, we see that the Greens and research types play the game because they receive $Billions (I'm not kidding) to solve the unsolvable. Money
Think about this. Before 1999 (or 2000-2001), had you ever heard the term "Invasive Species" or "Invasive Weeds"? 
Probably not. You had, however, heard the term "noxious weed".
The creation of the "Invasive Species" agenda was/is an ingenious attempt (successful so far) for the Green non-governmental organizations and government bureaucrats to hijack what was once a commonsense agricultural issue: noxious weeds.
Farmers and ranchers (as well as foresters and other resource folks) need to be on Red Alert so they don't fall into the "Invasive Species" trap.
The Greens will smile at you, as all parties agree on how "Invasive" knapweed is (true enough).
Producers must peel off the veneer and check out the websites and literature to see for themselves that it doesn't stop there.
The ultimate agenda is to target all nonnative species, including useful ones such as the clovers, timothy, etc.
Money is one of the two factors.
Power is the other -- and by far the more dangerous.
The Greens' intent is to wield power (and control) beyond that of the Endangered Species Act -- to use "Invasive Species" -- to control human behavior on public and private land.
It is a Trojan Horse.
